Bacteria combined with gold to produce "living material"

Scientists at MIT are developing hybrid materials that are a cross between living bacterial cells and non-living components such as gold nanoparticles or quantum dots. The resulting "living materials" are able to respond to their environment like regular living cells, while also doing things like conducting electricity or emitting light. Read More

Nano technique boosts plant energy production and creates plant biosensors

By - March 17, 2014 4 Pictures
In 2010, Stanford University researchers reported harnessing energy directly from chloroplasts, the cellular "power plants" within plants where photosynthesis takes place. Now, by embedding different types of carbon nanotubes into these chloroplasts, a team at MIT has boosted plants' ability to capture light energy. As well as opening up the possibility of creating "bionic plants" with enhanced energy production, the same approach could be used to create plants with environmental monitoring capabilities.

Need to filter some water? Just go peel a pine tree

By - February 28, 2014 1 Picture
In many parts of the world, the presence of harmful bacteria makes it vitally important that water from lakes or rivers be thoroughly filtered before being consumed. While materials such as silver nanoparticles and titanium dioxide will do the job, people in developing nations or rural settings typically need something a lot cheaper and easier to manufacture. As it turns out, wood from pine trees works great. Read More

Cochlear implants may be losing their awkward external hardware

By - February 10, 2014 1 Picture
Thanks to the development of cochlear implants, many people who would otherwise be quite deaf are able to regain a limited sense of hearing. Unfortunately, the implants also incorporate external components that can get in the user's way, and that look ... well, that look like the user has something hooked up to their ear. Now, however, researchers at MIT, Harvard Medical School and the Massachusetts Eye and Ear Infirmary have developed a chip that could lead to cochlear implants that are entirely implanted. Read More

MIT researchers clarify things with new transparent display technology

By - January 21, 2014 3 Pictures
There are a number of approaches currently used to create transparent displays, such as transparent OLED and LCD displays or simple reflection, however, most are limited in terms of viewing angle. Researchers at MIT have come up with a new system that is low-cost and offers a wide angle of view with the projected image appearing on the transparent material itself. Read More

Nanomaterial thermophotovoltaic system increases efficiency and portability of solar power

By - January 21, 2014 2 Pictures
It’s not a new idea to improve upon traditional solar cells by first converting light into heat, then reemitting the energy at specific wavelengths optimally tuned to the requirements of the solar cell, but this method has suffered from low efficiencies. However, new research at MIT using nanoscale materials finally shows how thermophotovoltaics could become competitive with their traditional cousins, and grant benefits such as storing solar energy in the form of heat to postpone conversion into electricity.
